Drag and buoyancy are two primary external forces acting on diving marine mammals. The strength of these forces modulates the energetic cost of movement and may influence swimming style (gait). Here we use a high-resolution digital tag to record depth, 3-D orientation, and sounds heard and produced by 23 deep-diving sperm whales in the Ligurian Sea and Gulf(More)

A fast, high-sensitivity detector is required for studies of environmentally relevant gases. Photoacoustic spectroscopy (PAS), an absorption spectroscopy technique in which absorption is detected as sound, is explored as a possible solution. A tuning-fork based PAS sensor is modeled using COMSOL Multiphysics. The model combines the acoustic and(More)
Over the last 40 years, there has been significant research effort directed towards the use of highfrequency narrowband acoustic scattering techniques to remotely investigate the distribution, abundance, and size of zooplankton on multiple spatial and temporal scales (e.g. Holliday and Pieper, 1980, 1995; Pieper et al., 1990; Napp et al., 1993; Wiebe et(More)
To measure and understand high-frequency broadband acoustic scattering in rivers and estuaries characterized by strong temperature and salinity gradients and intermittent and often high plankton and particle concentrations and dissipation rates of turbulent kinetic energy. To use these measurements and understanding to develop a remote sensing tool for(More)
